For the first time, bimetallic Ni–Co selenides with different Ni and Co ratios have been synthesized and used as electrode materials for high-power energy storage. Owing to the synergistic effect between Ni and Co, bimetallic Ni–Co selenides, especially for Ni₀.₆₇Co₀.₃₃Se, show higher specific capacity and improved rate capability combined with excellent cycling stability than the monometallic Ni or Co selenide.
